In step 20, it is determined whether or not the electrical conductivity is zero. Whether or not the operation time Tx is zero is determined. If the operation time Tx is zero, the operation possible time T1 of (Table 1) is set in step 22. When the humidification operation is started in step 23, the operation time Tx is measured and recorded in step 24, and it is determined whether or not the operation time Tx is larger than the operation time T1 minus the predetermined time A in step 25.

In addition, since the hardness and electrical conductivity of water are almost inversely proportional, the operation time up to the cleaning time of the humidifying filter 7 can be set by the measured value of the electrical conductivity of the water. It is possible to prevent the humidification ability from being reduced due to adhesion.

  In addition, since the electric conductivity measured by the measuring means 11 is zero when the use of the humidifying filter 7 is started, the humidifying filter 7 is installed in the main body 4 after new or cleaning, and then the operation switch of the main body 4 is operated. 14, the measuring means 11 measures zero electrical conductivity in a state where there is no water in the water tank 10, and the control means 12 determines that the humidifying filter 7 is started to be used from the measured value, and determines the operation time Tx. Is set to zero. Moreover, after water supply, the operation possible time T1 until the washing | cleaning time of the humidification filter 7 which is the next step is set.

  When water is supplied to the water tank 10 before the measuring means 11 is energized, the operation time Tx can be set to zero by using the reset switch of the operation switch 14.

(Embodiment 2)
As shown in FIGS. 1 to 4 and 6, the control means 12 measures and records the stop time Ty together with the operation time Tx. Next, from the operation time Tx, the operable time T1 is set according to the above (Table 1), the stop time Ty is substituted into (Equation 1), the operable time T2 is calculated, and the operable time is reset. ing.

  The operation of the humidifier having the above configuration will be described with reference to the flowchart of FIG.

To do. In step 37, the operation time Tx is measured and recorded, and in step 38, the operation time T2 is set based on the operation time Tx, the stop time Ty, and (Equation 1). In step 39, it is determined whether or not the operation time Tx is greater than a time obtained by subtracting the predetermined time A from the operation possible time T2. When the operation time Tx is larger, the display lamp 16 is lit in step 40 and the replacement time of the humidifying filter 7 is approaching. This is notified, but the operation is continued. In step 41, it is determined whether or not the operation time Tx is greater than the operable time T2, and if it is greater, the operation is automatically stopped in step 42, and the display lamp 16 blinks and is displayed in step 43. Inform.

  If it is determined in step 39 that the operation time Tx is smaller than the time when the predetermined time A is subtracted from the operable time T2, or if it is determined in step 41 that the operation time Tx is smaller than the operable time T2, step 37 is performed. It will return to.

  As described above, according to the second embodiment, the control unit 12 measures the operation time Tx and the stop time Ty, and can change the settable operation time T1 of the humidifying filter 7 to the driveable time T2. When the stop time Ty is longer than the operation time Tx of the main body 4, the humidification filter 7 may be clogged due to other factors such as adhesion due to drying of the surface of the humidification filter 7 and bacterial growth. Assuming the phenomenon, the operable time T2 obtained by shortening the humidifying means 8 from the stop time Ty by the conversion equation (Equation 1) is reset.

  Thus, the clogging of the humidifying filter 7 may proceed while the operation of the humidifying device is stopped, and the operable time T2 until cleaning of the humidifying filter 7 is reset according to the length of the stop time Ty. Thus, the cleaning time according to the use state can be obtained.

(Embodiment 3)

  Here, Tw is the operation time when the amount of blown air is maximized.

  The operation of the humidification operation having the above configuration will be described with reference to a flowchart.

  In step 44, the humidifying operation is performed. In step 45, the operation time Tw at the maximum blowing time is measured and recorded. In step 46, the operation time Tx of the humidifying device is measured and recorded. From the time Tx, the operable time T3 is set using (Equation 2). In step 48, it is determined whether or not the operation time Tx is greater than the time obtained by subtracting the predetermined time A from the operation possible time T3. If so, the display lamp 16B is turned on in step 49, and the operation time Tx is operable in step 50. It is determined whether or not it is greater than time T3, and if it is greater, the operation is automatically stopped in step 51, and the display lamp 16 is blinked and notified in step 52.

The drivable time T3 can be calculated and reset in response to the phenomenon that the amount increases and the dampness of the humidifying filter 7 increases and the drivable time T3 until the humidifying filter 7 is cleaned becomes shorter.

  That is, when the amount of air blown temporarily increases, the amount of humidification increases, and the amount of impurities adhering to the humidifying filter 7 increases in parallel. Therefore, a variable element of the operation time Tw at the time of maximum air blowing is incorporated, By resetting the operation time T3 until cleaning, the time until cleaning of the humidifying filter 7 can be set correctly.

In step 58, it is determined whether or not the operation time Tx is greater than the time obtained by subtracting the predetermined time A from the operation possible time T4. If it is greater, the display lamp 16 is turned on in step 59. In step 60, it is determined whether or not the operation time Tx is longer than the operable time T4. If it is longer, the operation is automatically stopped in step 61, and the display lamp 16C is flashed and notified in step 62.

  If it is determined in step 58 that the operation time Tx is less than the time obtained by subtracting the predetermined time A from the operation possible time T4, or if it is determined in step 60 that the operation time Tx is less than the operation possible time T4, the process returns to step 55. .

Since the setting of T4 can be changed, when the hot air operation time is long, the humidification amount increases, the dirt of the humidification filter 7 increases, and the operable time T4 until cleaning of the humidification filter 7 can be set short. it can.

  That is, the amount of humidification increases in the warm air operation compared to the warm air operation, and the amount of impurities adhering to the humidification filter 7 increases in parallel. Therefore, the warm air operation time Tz is measured to clean the humidification filter 7. By resetting the operable time T4 until the time until the humidifying filter 7 is cleaned, it is possible to correctly set the time.
